Hi @stefanprodan,

First of all great repository and thanks for sharing. I noticed that on recent versions of Docker prometheus can't discover other nodes, more specifically,

I'm pretty sure the problem is that prometheus is not able to discover the node-exporter on other nodes. I would be happy to adapt the package to a newer docker version. Can you provide some guidelines on how to debug or where to look?

I guess the ingress network of docker was not working. I'm closing down this issue
